The interface with Yacas is very elementary. Someone would have to write
a small file for converting TeXmacs expressions into Yacas input,
like we did for many other systems; see

        plugins/macaulay2/progs/m2-input.scm
        plugins/maxima/progs/maxima-input.scm
        plugins/r/progs/r-input.scm
        etc.

and

        progs/texmacs/plugin/plugin-convert.scm

If someone volunteers for spending one or two hours on this;
this should not take too much time if you know the Yacas
syntax well enough.
